Hum of Gravitational Waves from Giant Black Holes Causing Millisecond Pulsar Variance
Astronomers turned networks of dead stars into galaxy-size gravitational wave detectors, radio astronomers have tuned into the slowly undulating swells in spacetime thought to arise from pairs of supermassive black holes (SMBHs) that are about to collide. We are improving instruments and creating new instruments to improve our gravitational map of the universe. “As a …
